7 Claims. "i

.This invention relates to safety razors ofmagazinetype, andparticularly to a razor :of this type in which the blade is a continuousthin flexible strip preferablyhaving both edges sharpened.

. It further relatesto a-razor of the type in-which the blade strip .iscompactly. coiled and is fed from this coil into position for use, andmore particularly toa structure ofathistype in which provision. is .madefor receiving and storing the used blade strip. I

vIt further relates toa-razor of this typein which the blade magazineisxa replaceable unit in which is packaged a-roll of blades for use'andinwhich provision is madeto receive the used portions of the blade.

parts of. the razor andafter exhaustion of the strip be detached; and

it further. relates to a. safety razor of thereplaceable magazine typeinwhich the "magazine .and used blade therein is removed and thrown awayand is replaced by a new unit.

The objects of the-invention are: To provide an improved. safety.razor-of flexv iblestrip .blade type;

.To provide an improved safety razor of strip blade type having vareplaceable blade carrying magazine adapted to receiveand store.the-blade .strip as it is used;

'To provide a removable. blade carryingmaga- .zine adapted to storeand.remove the blade strip for disposal;

'-':*o provide 'a's'afety'razor of magazine type in which a continuousblade strip having sharpened edges is adapted to be fed manuallyfrom the"magazine into cutting position and the used portions of thestripareconcurrently fed back into 'the magazine for storage;

To provide means for centering'the'b'lade within the magazine andagainst damage to the blade edges-as the blade is fedinto cuttingposition;

Toprovide means forwithdrawing the'blade from themagazine and advancingit to shift successive portions "into cutting position; and

To provide'blade retracting means for prof' moting storage of'usedportions of the blade strip.

Referring now. to the drawings in which the various parts areindicatedby numerals:

Fhe razor includes a tape-like strip of thin flexible metalhavingitsopposite edges sharpened to form a long narrow double edge blade I B,which ishoused in a .hollow body, including a head portion l8 and ahandle portion 20, and-a complementary magazine. 22 which telescopeswithin the bodyv portion.

Initially the blade is housed in a coil 24 within the magazineunusedportions l6A of. the blade being successivelywithdrawn from the coil andfedacross. the head portion l8 for use, the used portions [6B beingconcurrently returned into the storage section of themagazine, and thereformed .into aused-coil 24A.

Thehollow body 20 is substantially of rectangular cross section withside Walls 20A, and edgewalls 20B,- anis open at its lower end. Theupper end or head portion iii of the body includes a blade support 28which is arcuately curved in cross section, and extends beyond thecutting edges of. theblade l 5 and slightly beyond the side walls ZllAtoform guards 28A. The blade support is provided with longitudinal slots2813 which underlie and expose the cutting edges of the blade l6 foruse.The slots in cross section extend downwardly and outwardly and dischargeexteriorly to the body below the guards 28A. Im- .mediately adjacent theedge walls'ZflB the blade amaooc support 28 is cut away, as is shown inthe upper right corner of Fig. 5 from which the guide sprocket has beenremoved, to form slots C, and the sprocket chambers 20D. Overlying theblade is a holding member which holds the blade against the bladesupport 28, the member at its opposite ends curving arcuately downwardand connecting into the edge walls 203.

In the sprocket chambers 20D the support member 28 is provided withbosses 32, which carry shafts 34, and pinions 36 which are centrallydisposed between the side walls 20A, the shafts being positioned toproject the teeth of the pinions through holes 38 alined along thelongitudinal center of the blade strip, and so engaging to aline theblade strip [6 as it leaves the mesazine 22, passes across and leavesthe head IS.

The blade magazine 22 includes side walls 22A and edge walls 223, thelatter walls being joined at their lower ends by an arcuate continuation22C which forms the bottom end of the magazine, the upper end of themagazine preferably being closed by a top 22D. Within the magazine anarcuate continuation 22E of the bottom end 220 establishes a chamber 22Ffor the reception with openings 22G adjacent the edge walls 22B for theexit of the unused blade portion [6A and the entrance of the usedportion lfiB of the blade strip. Preferably a guide member 22H restrictsdeflection of the blade portion {5A between the coil 2% and the openin22G and a similar guide member, not numbered, may be used adjacent theopposite opening 22G through which the used strip IBB reenters themagazine. The edge walls 22B are provided with longitudinal slots 22.]extending upward from approximately the center of coil 24 into adjacencyto the top of the magazine for a purpose to be hereinafter disclosed.The side walls 22A carry hubs 48 which journal a shaft 42 on which ismounted a sprocket 44 about which the coil 24 of the blade is formed,the sprocket having projecting teeth which engage the central holes 38in the blade and prevents its lateral displacement and consequentcontact of the blade edges with the sides of the magazine. The sidewalls of the magazine are also apertured to remagazine and the body areof light weight metal or plastic and that the side walls 22A of themagazine in the vicinity of the lugs 46 may be inwardl deflected toeffect release of latching engagement of the lugs 46 therewith when itis desired to remove the magazine, deflection of the side walls of thehandle permittin outward deflection of the lugs during the subsequentremoval.

Preferably both edge walls 2GB of the handle intermediate their lengthare outwardly deflected to form charmelways 48 which are respectivelyprovided each with a longitudinal slot 48A positioned to aline with aslot 22J of the magazine 22 when the same is in place, the slottedchannelways slidably mounting manually operable blade shifters and 52having toothed portions 50A, 52A, which extend through the slots 22J ofthe magazine into engagement with the holes 38 of the blade stripportions [6A and |6B respectively. The teeth of the toothed portions50A, 525 are of triangular shape and are respectively faced for shiftinengagement with the blade holes only during upward movement of theshifter 50 and downward movement of the shifter 52 whereby toconcurrently move the blade portion I6A upward toward the head l8 andwithdraw the blade portion 163 from the head and feed it into thestorage portion of the magazine. Preferably the slots 22J of themagazine and 48A of the channelways are of length to allow propershifter movement to accomplish a complete cutting sector shift of theblade in the head.

Initially the razor is sold as a unit including the body section andblade equipped magazine section, ready for use.

The shifter 58 is retracted bringing the tooth portion 50A intoengagement with the holes in the blade strip and the shifter issubsequently moved upward the length of the slot 22J shifting the bladeupward through the opening 226 toward the sprocket 35. The shifter isagain retracted, and the operation repeated advancing the blade aroundthe first of the sprockets 36 and across the head until a length ofblade has been advanced into cutting position, and preferably intoengagement with the second of the sprockets. When after use, the razorrequires a fresh section of blade, the shifter is again operatedshifting a new cutting length into position in the head and forcing theused portion IGB downward along the edge wall 20B of the body andthrough the opening 22G into the magazine 22, and thereafter both theshifter 50 and the shifter 52 may be jointly operated, the first toposition the blade toward the head and the second to concurrently aid inwithdrawing it from the head. Eventually the used portion [6B of theblade is forced downward and into the chamber 22F in which by subsequentadvancement the used section is coiled.

It will be understood that in advancing the blade it is usuallynecessary to advance the cutting edge less than the full length exposedfor use, since ordinarily the blade in the central portion of the headdoes the majority of the work. Under such conditions it is obvious thatonly such movement of the shifters need be made as is found necessary toaccomplish the desired shift.

When the entire strip of blade has been used and the used blade ishoused within the magazine the side Walls 22A of the magazine aredeflected in the vicinity of the lugs 46 to release the lug engagementand the magazine withdrawn, the subsequent outward defiection of the lugcarrying portion of the body walls 20A permit-ting completion of theremoval. The magazine removed is thrown away and replaced with a newreplacement unit and the operation repeated.
